Respiration Disorders

The goal of this clinical trial is to learn whether elastic-band resistance training, with or without breathing training, can improve lung function and physical function in older adults with pulmonary function impairment living in the community. It will also learn about the safety and feasibility of these exercise programs. The main questions it aims to answer are: Does elastic-band resistance training improve lung function, lower-limb muscle strength, walking ability, and exercise tolerance? Does adding structured breathing training to elastic-band resistance training provide additional benefits for lung function and respiratory-related health status? Are these exercise programs safe and acceptable for older adults in a community setting? Researchers will compare three groups: elastic-band resistance training plus breathing training, elastic-band resistance training alone, and usual health education. This will help determine whether elastic-band resistance training is helpful and whether breathing training adds extra benefit. Participants will: Take part in a 12-week study Be assigned by chance to one of three groups Attend supervised exercise sessions 3 times per week if assigned to an exercise group Receive usual health education and daily activity guidance Complete lung function tests, muscle strength tests, physical function tests, and questionnaires at the start of the study, at 6 weeks, and at 12 weeks

Respiratory complications are among the leading causes of death in patients with chronic spinal cord injury (SCI). Our previous work showed that pulmonary function can be improved by using our original respiratory training method. However, the effectiveness of this intervention is limited due to the disruption of brain-spinal connections and consequently lowered spinal cord activity below the injury level. Our recent studies showed that electrical stimulation of the spinal cord below the level of injury leads to increased ventilation which indicates activation of the spinal cord structures related to respiration. These findings indicate that spinal cord stimulation can be a promising therapeutic additive to the treatment. The goal of this study is to justify the establishment of a new direction in rehabilitation for patients with SCI by using a non-invasive spinal cord stimulation in combination with respiratory training. Our aims are: 1) to evaluate the effects of such stimulation applied to the injured spinal cord on pulmonary function and respiratory muscle activity, and 2) to evaluate the effectiveness and therapeutic mechanisms of the spinal cord stimulation combined with respiratory training. Thirty-six individuals with chronic SCI will be recruited and assigned to three groups to receive respiratory training or spinal cord stimulation alone or a combination of them. All participants will be tested before and after cycles of experimental procedures with/or without stimulation. Our hypotheses will be confirmed if the respiratory training combined with spinal cord stimulation results in the most enhanced positive effects.

Sedation is essential for mechanically ventilated pediatric patients to ensure comfort, ventilator synchrony, and prevention of self-extubation. However, excessive sedation may prolong mechanical ventilation and ICU stay, while inadequate sedation may cause agitation and physiological distress. Continuous Sedation Infusion (CSI) and Daily Sedation Interruption (DSI) are two commonly used strategies. Limited data exist comparing their impact on comfort levels in pediatric patients. This randomized controlled trial aims to compare comfort scores between continuous Midazolam infusion and daily sedation interruption in mechanically ventilated children aged 5-10 years diagnosed with pneumonia. Comfort will be assessed using the COMFORT-B Scale and Richmond Agitation-Sedation Scale (RASS) every 6 hours for 72 hours. The study intends to determine which strategy better maintains optimal sedation and comfort in pediatric intensive care settings.

Aim of the research: To find out why antibiotics work differently in certain patients with severe pneumonia and sepsis. Background: Individuals can become very unwell from pneumonia, sometimes requiring admission to hospital or even the intensive care unit (ICU). In some cases, pneumonia can lead to a condition called sepsis, which can be deadly if not treated quickly. In the UK, approximately 30,000 patients die from pneumonia every year. Clinicians use antibiotic injections to treat life-threatening infections such as severe pneumonia. After being injected into the bloodstream, antibiotics quickly spread throughout the body, attacking the infection. Antibiotics are eventually broken down and removed from the body by the kidneys and other organs. However, antibiotics fail to achieve the same consistent result for every patient. This may be to do with the way the antibiotics travel through and are removed from the body, leading to different antibiotic levels in the blood at any one time. Low antibiotic levels can result in worse outcomes and antibiotic resistance. Patients can be grouped based on how their immune system reacts to infections. The SIPRES Study aims to explore if these previously described groups explain the difference in antibiotic levels in patients with severe pneumonia and sepsis. Procedures: We will study how adult patients with severe pneumonia respond when treated with the most commonly used antibiotic in the ICU called piperacillin/tazobactam. Alongside information on how quickly patients get better and how long they need to stay in hospital or in ICU, we will collect blood samples to measure antibiotic levels and assess each patient's immune system at two time points during their treatment. This will allow us to measure antibiotic levels in blood at different times and group patients based on their immune system reaction to infection. We will describe the range of antibiotic levels seen in the different immune system reaction groups using mathematical and statistical models. Patient involvement: We are working closely with people who have experienced severe pneumonia and will work with two patient partners and a patient advisory group to help shape this research. Patient contributors have already shaped the development of the funding application and identified important study outcomes. Patients we have spoken to are concerned over the appropriate dosing of antibiotics and appreciate the need for improved and precise approaches to treating severe infections. Moving forward, patient partners will help finalise the protocol, develop patient and public facing materials, provide their perspective on the study results and shape plans to share the outcomes of the study more broadly. Potential impact: The SIPRES Study will help identify a group of patients at risk of low antibiotic levels in blood, who are less likely to improve with treatment and more likely to develop antibiotic resistance. Mathematical models that can help clinicians personalise antibiotic dosing for each critically ill patient with severe pneumonia will be developed. Findings have the potential to limit the development of antibiotic resistance and help patients survive and get better faster so that they can return to their normal daily lives. Individualised dosing for patients with low antibiotic levels, as opposed to 'one size fits all' prescribing, also has the potential to more efficiently allocate scarce resources to those who will benefit the most.

The aim of this study is to observe the effect of distraction methods on children aged 3-6 years who apply to the emergency department due to respiratory complaints and receive inhaler medication.

Exploring the effect of aerobic exercises on lung function, chest movement, and exercise capacity in women suffering from fibromyalgia.

Obesity Hypoventilation Syndrome(OHS) is characterized by daytime hypercapnia and sleep-disordered breathing without other causes of hypoventilation in individuals with a body mass index above 30 kg/m2. It is stated that obesity is at the basis of the metabolic changes seen in individuals diagnosed with OHS. Also sedentary lifestyle habits, which are common in obese individuals, cause the risk of sarcopenia due to loss of muscle strength and mass, accumulation of adipose tissue in the body, and decreased exercise capacity. Reduced exercise capacity due to obesity has been shown in the literature to strongly interact with mortality risk. As a result of obesity and all this negative picture, impaired emotional state and decreased quality of life are observed in individuals. Simultaneously, sleep parameters are also negatively affected. In particular, increased adipose tissue leads to loss of muscle mass and strength, increased risk of sarcopenia and sleep-related problems. The association of obesity and sarcopenia is referred to as 'sarcopenic obesity'. Sarcopenic obesity is defined as the coexistence of sarcopenia and obesity. The concept of sarcopenic obesity has recently taken its place in the literature. In particular, there are very few studies on its relationship with sleep parameters. However, while obesity is the basis of OHS, there are no studies on the presence and effects of sarcopenic obesity in this patient group. Based on this point, we aim to investigate the effects of sarcopenic obesity on sleep parameters, exercise capacity and quality of life in individuals with OHS.

The goal of this single-centre observational study conducted at the Royal Hospital for Children in Glasgow, Scotland, is to employ a multi-omics approach to investigate the "gut-lung axis" in health and disease. Part A is a cross-sectional study design investigating the postulated bidirectional link between the gut and lung microbiomes in children suffering from respiratory or gastrointestinal conditions. Children with no GI or respiratory issues attending for orthopaedic care will be used as a benchmark for a healthy gut-lung axis. The main questions we aim to answer are: * What does a healthy gut-lung axis look like? * Do children with respiratory issues show an altered gut microbiome? * Do children with GI issues show an altered lung microbiome? Part B is a longitudinal study design, that aims to assess the effects of biologics on the gut-lung axis by comparing the gut and lung microbiomes in children with asthma at two time-points who are indicated to start biologics therapy (Asthma treatment) or will not receive biologics therapy (asthma control). Participants will provide: * airway samples (to investigate the lung microbiome) * blood samples (to assess inflammatory and metabolic factors which may mediate communication between the two sites) whilst under general anaesthetic for a treatment related to their standard of care * stool samples (to assess gut microbiome) * dietary information (food diary and/or food frequency questionnaire) to assess relationships between diet and the gut-lung axis.
